You should be able to peg that to whatever you're using to determine the
position of the planet in the animation.

So just use a torus, or section of scaled torus, or an elliptical sphere sweep
that starts at zero, and goes to wherever your planet currently is.

I managed to use a Dupin cyclide - but nevermind me.

Have you managed to determine how all the planets are aligned at some initial
starting point?
